Assumptions

Conventional: upfront fee none, annual mortgage insurance none; fee schedule effective January 1, 2026.

Mortgage rate: 7.254% for a 30-year fixed loan (Optimal Blue daily, published November 12, 2026). Your actual rate depends on your credit, loan type, and lender.

Down payment: 20% of the list price. PMI is included when the down payment is below 20%.

Property taxes: based on the listing's reported annual tax. Taxes are often reassessed after a sale, so your amount may differ.

Home insurance: estimated at about 1% of the price per year. Florida premiums frequently run higher than the national average -- get a real quote before relying on this number.

HOA dues: taken from the listing's association fees. One-time special assessments and capital contributions are not included.

Affordability bands: based on common debt-to-income guidelines (about 28% of income toward housing, 36% toward total debt). Individual lenders set their own limits.

This is an illustrative estimate, not a Loan Estimate, quote, or credit decision. It uses common debt-to-income guidelines and the current published 30-year rate. Actual costs and loan terms require pre-qualification with a licensed lender.
